Faucet Company, Chicago, Ill.,
of Illinois a kcorperation Application July I3, i939, Serial No. 284,320
I Claim.
This invention relates to improvements in faucets and is here shown as applied to a self-closing faucet.
Among the features of my invention is the provision of a removable unit including a sleeve withv means for preventing entrance of water (or other fluid being controlled) into the upper part of the eeve. In a device'of this kind, the removable sleeve contains a spring and other working parts; and it is desirable to keep these parts free from the fluid being passed through the faucet.
Another feature of my invention is the improved dash pot for checking the closing of the faucets.
Other features and advantages of my invention will. appear more fully as I proceed with my specification.
In that formof device shown in the accompanying drawing- Figure 1 is a vertical sectional View; Fig. 2 is a View taken as indicated by the line 2 of Fig. 1 on an enlarged scale; Fig. 3 is an enlarged vertical sectional view of the cap; and Fig. 4 is a bottom view thereof.
As shown in the drawing, ID indicates a casing open at the top and provided with an inlet opening II at the bottom and an outlet opening I2 at one side. I3 indicates a sleeve in the casing with an inlet opening I4 atrthe lower end. The lower end of this sleeve I3 carries a seat l5 (here-shown as removable from the sleeve) The sleeve It is also provided with a plurality of outlet openings It discharging into the outlet I2 in the casing III.
The top of the casing is closed by a cap Il. I?. indicates a vertically movablemetallie stem extending through the sleeve. The lower end of this stem projects through the inlet opening I4 in the lower end of the sleeve I3 and carries a valve disc I@ adapted to seat upon the seat I5 to close the faucet when the vertically movable stem IE reaches the upper limit of its movement. Downward movement of the stem I8 is adapted to remove the disc I9 from the seat I5 to open the faucet.
I8a indicates an extension of the stem I8 telescoped over the upper end thereof extending through a central hole in the cap I'I and provided at its upper end with an operating handle 20. The lower end of this member Illa carries cam surfaces 2I cooperating with cam surfaces 22 in the cap I'I so that rotation of the member I 8a will lower the cams 2I to cause them' to engage the collar 23 on the stem I8 to depress the same against the tension of the spiral spring (i. RSI-1353) The cam surfaces on the cams 2|, 22 are steep enough' so that when the handle 2i! is released, the spring 24 will force the stem I8 upwardly to close the faucet.
The lower end of the sleeve I3 above the por It? is providedk with an internal annular shoulder .25 above which-is provided the packing 26, washer 2l' and gland 28, the latter being engaged by the lower `end of the spring 24. The packing 26 prevents water from entering the sleeve I3 above the shoulder 25 and thus protects the spring24 and other working parts of the faucet from attack by the liquid bein-g passed through the faucet.
The' cap' Il is heldin position tightly on the upper end of the casing II) by means of the nut 29.
'indicates a dash pot cylinder removable through the upper end of the casing III after-the cap Il, sleeve I3 and stem I8 have been removed. Ordinarily. in removing these parts, the dash pot cylinder will come up with them owing to the friction of the plunger therein. The cylinder 35 is provided with an outwardly projecting flange 35a at its upper end adapted to be gripped be tween the'upper portion I5a of the seat I5 and the internal shoulder IIBa in the casing Il. In` general terms it may be stated that the flange 35a is gripped between the lower end of the sleeve I3 and the portion of the casing Ill (internal shoulder Illa) surrounding the inlet opening II. Since the sleeve I3, as here shown, carries on its lower end a removable seat I5, it may be more accurate to state that the flangea on'the cylinder 35 is gripped between a portion of the removable seat I5 and a portion of the casing I0 surrounding the inlet opening II. Since the upper part of the seat I5, however, does not function as a seat, it may broadly be considered as a part of the lower end of the sleeve I3 or the equivalent thereof. In constructions similar to this, the lower end of the sleeve I3 may have a seat formed integral therewith. In such case, the flange 35a would be gripped between the lower end of the sleeve (such lower end being integral with the sleeve) and a portion of the casing (internal shoulder Ita) surrounding the inletvopening II. In describing and claiming the invention, therefore, it is proper to state in broad terms that the flange 35a is gripped between the lower end of the sleeve and a portion of the cas'- ing surrounding the inlet Il.
The lower end of the stem I8 is provided with a piston or cup washer 33 operating in the cylinder 35. Above this piston, the cylinder 35 is dicated by 45.
provided with holes or inlet openings 35h for the flow of water.
38 indicates a nut on the lower end of the stem i3 to hold the disc i9 and piston 36 thereon. 39 indicates a spacing member and 40, a washer.
Mounted in the lower end of the cylinder 35 is a spring @l with its lower end 42 extending through the hole 43 in the bottom of the cylinder, As here shown, the cylinder is provided with an extension 4@ in which this hole is formed. The lower end of the wire 42 is iiattened, as in- The hole 43 is a port or bleed hole to permit the flow of Water therethrough to permit vertical movement of the cup Washer or piston 36. The size of this hole Will regulate the speed of closing of the faucet. Since this hole is ordinarily Very small, there is danger of its becoming clogged up. I prevent this by inserting through the hole 43 the Wire 42 which is moved downwardly every time the stem I8 is lowered and which again is raised by the spring 4I whenV the faucet is closed. This movement of the wire 132 in the hole @3 keeps it clear and free of obstructions.
While I have shown and described certain em'- bodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made Without departing from the spirit and scope of my invention as disclosed in the appended claim, in which it is my intention to claim all novelty inherent in my invention as broadly as permissible, in view of the prior art.
What I claim as new, and desire to secure by Letters Patent, is:
A faucet, including: a movable stem carrying a valve; a dash pot cylinder; a piston on the valve stem in the dash pot cylinder to retard closing of the valve; a port in the cylinder; and a spiral spring in the cylinder, said spring having its upper end bent downwardly and extended through the port, said spring adapted to be engaged by the valve stem upon movement thereof, wherebyk the port is kept freev and clear of obstructions.
